Readers who have a long memory and a history of online trading may also vaguely recall that the creator of the famous PGP (Pretty Good Privacy) software, security expert Phil Zimmermann, launched a "Pgpfone" in 1996. of Internet telephony products. About three years later, broadband networks really started to grow. This is the early stage of the network telephony development cycle. Pgpfone a little too far ahead, not to arouse people's attention. But the world must be careful! Security expert Ph

When you look at a VoIP solution, one of the most difficult problems to solve is the labor cost problem. The difficulty of this issue may be second only to the quantification of the impact on user productivity. This is partly because the vendor promises that such integration will reduce staffing while doing marketing, so that your mind will have the impression of reducing staff. However, integration and technical support are new technologies. This tec

I. architecture of the billing systemThe design of the VoIP Billing system follows the design principle of real-time Internet billing, and features real-time, stability, reliability, portability, and scalability. The function design not only takes into account the basic functions of the Internet billing system, it also considers users' needs and the business characteristics of the VoIP system.The core part

above practices and other power-saving strategies, the ROCm chip can improve the power consumption efficiency of WLAN operations, which is up to six times better than the traditional WLAN Chip, thus improving the battery life. A new generation of 802.11 devices that can implement various VoIP applications now include such chips. Import voice to WLAN 802.11 WLAN can use high-performance components to provide reliable overall performance. However, this

The combination of multimedia applications and traditional enterprise networks has become commonplace in enterprises. In particular, with the steady development of VoIP technology, IP voice has gradually become an indispensable new member in the enterprise network. However, this poses new challenges to enterprise network security. Recently, more and more attacks have been initiated against enterprise VoIP a

In traditional speech, we all communicate in Wired form. The first time was a analog signal, followed by a digital signal. Now, our voice communication methods can be implemented through network IP addresses. This leads to today's topic-VoIP and VoWLAN. VoWLAN Overview VoWLAN is one of the emerging applications of WLAN. VoIP transmits voice signals through a data network; WLAN), and uses wireless access poi

QoS can give priority to voice communication services under limited network resources. However, if too many voice communications occur, the network may be congested. How can this problem be solved?Call Control for enterprise VoIP networksWhen we configure the QoS function that supports voice on an enterprise's IP network router and switch, this IP network is ready to carry the voice application. However, in order to achieve the call, we also need to e

the Internet can make full use of the network and increase the chance for students to communicate and communicate with the outside world, the cost of communication between students and schools is reduced. However, this communication method requires less investment in the early stage, which is convenient to use and must meet the personalized communication characteristics of students, another important selling point is long calls and low costs. II. Introduction to

Application VoIP service quality (QoS) has four key steps: Application VoIP service quality (QoS) has four key steps. If you do not follow these four steps, your VoIP implementation will not realize its full potential. In addition to enabling the vro function, QoS has many things to do. Therefore, it takes some time for you to plan and design the correct QoS for

I. Overview As we all know, a company's business activities depend heavily on modern communication methods. Exchange of telephone, fax, data, and information is the fundamental guarantee for the survival and development of enterprises. At the same time, the extensive use of these devices has brought a burden to enterprises and increased their operating costs. In particular, large international groups and large enterprises have paid a lot of money for this. In recent years, with the continuous de

In the case of Voip, we often encounter customer requirements for public-specialized functions. The general practice is to connect the FXO interface to the extension line. The customer calls in through the external line, hears the automatic operator, then dials to the VOIP extension, and then calls the IP address, however, this practice usually requires some vswitches. PBX has a type of group telephone. T

QoS Assurance Measures for VoIP services are currently the topic most discussed in the industry. IETFInternet Engineering Task Force) several technical solutions to support QoS are recommended, mainly including: Integrated Service Int-serv) /Resource Reservation Protocol (RSVP), Differentiated Services (DiffServ), Multi-Protocol Label Switching (MPLS), and business Traffic Engineering (Traffic Engineering. Telecom operators have also adopted some meas

When enterprises integrate data centers and voice technology, they may consider meeting the environmental conditions required for the operation of new devices in advance. However, when enterprises switch from a TDM-based phone to an IP phone, meeting the needs of the wiring room environment is often ignored. When deploying an IP phone to a desktop, users will soon face the same problems as local broadband providers. These problems may cause the system to fail to run normally, or cause higher cos
